Appears to have been nickel silver plated - this is worn off with only a bit remaining in recesses

The square marble base appears to be newer and is marked with an Italy tag - The cherub sits securely on it

The marble has loss to one upper corner as well as some smaller chips it measures 5 1/2" Square and 3/4" Tall

The lamp to the Top edge measures 11 3/8" ( The cherub is 10 1/2" Tall)

I am not positive about the metal content - a magnet does not stick 

The bow and arrow and the Cast decorative pedestal that the cherubs knee is on are separate from the cherub figure and appear to be cast brass and bronze respectively

Detail is lovely - One wing has a crack - that extends about 1/3 of the way dowm , this is completely stabile and is not loose or coming off

the top fitter is 3 1/2" Diameter

( I believe this was an oil lamp -  as there is no wireway)
